我正在嘗試使用twitter4j 3.0.5的簡單twitter搜索示例。當我運行這個樣本沒有代理這是工作，但在代理它如下拋出一個異常：twitter4j 3.0.5：sun.security.validator.ValidatorException：PKIX路徑構建失敗

請讓我知道是否有這個問題的解決方案。

該問題與twitter4J中的SSL支持有關。 Twitter已棄用2014年1月14日對普通HTTP請求的支持。您必須在每個請求中使用HTTPS。當您在Tomcat服務器中添加CA證書時，您的問題就會解決。

你能告訴如何？ – saplingPro

DeepakGangore是正確的

這花了我組織了幾個試驗在我們的督促預ENVS以確定我們的n層堆棧上的所有運動部件，屬於根CA和第三方庫。

對於我的組織......的解決辦法是：

1）更新twitter4j庫是版本3.0.5
2）更新應用程序服務器JDK安裝的JRE cacerts文件，與JDK JRE7版本。

這個組合，解決了我們的應用程序能夠與api.twitter.com端點交談的能力。
